In a medium pot, cover the potatoes with water. Cover pot and bring to a boil over high heat. Remove the lid and cook until the potatoes are tender but not falling apart, 4 to 5 minutes.

Meanwhile, season the chicken lightly with salt and aggressively with pepper. Combine the rosemary, garlic and 2 tsp. lemon zest, then rub over the chicken. Wrap each chicken thigh with 2 slices of the pancetta.

In a large skillet, heat the EVOO, three turns of the pan, over medium-high. When the oil begins to ripple, add the chicken and brown until crispy, about 3 minutes per side. Add the wine, shaking the pan for 1 minute. Add the stock and reduce the heat to medium. Simmer until the chicken is cooked through, about 8 minutes, then remove to a warm plate and cover.

Drain the potatoes, then add them to the skillet, turning to coat in the sauce. In a medium bowl, dress the arugula with the lemon juice and EVOO; season. Serve the chicken with the potatoes and salad.
